God's mercy is from everlasting to everlasting. David understood that while men and women were frail, weak and bound by time the Lord loved His own from before time and promised to gift them everlasting life. David's psalm is a testimony to God's everlasting love to His elect in the covenant of grace.

David is teaching the church about the mercy, grace and love of God in Christ. He explains the dimensions of mercy and the pity of God for those who love and honour Him in the Lord.

The gospel of the Lord Jesus Christ was known and believed by God's servants of long ago just as surely as it is known and believed by His people today. David tells us that Christ made known his ways unto Moses so that Moses knew the gospel of distinguishing, sovereign grace and substitutionary atonement.

Luk 14:12 Then said he also to him that bade him, When thou makest a dinner or a supper, call not thy friends, nor thy brethren, neither thy kinsmen, nor thy rich neighbours; lest they also bid thee again, and a recompence be made thee.

Luk 14:13 But when thou makest a feast, call the poor, the maimed, the lame, the blind:

Luk 14:14 And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just.

David's psalm of praise to God is a call to us all to bless the Lord from our soul for all His benefits. David expounds what these benefits are and calls every child of god to testify with him to the grace, mercy and love of God in Jesus Christ.

Luk 14:7 And he put forth a parable to those which were bidden, when he marked how they chose out the chief rooms; saying unto them,

Luk 14:8 When thou art bidden of any man to a wedding, sit not down in the highest room; lest a more honourable man than thou be bidden of him;

Luk 14:9 And he that bade thee and him come and say to thee, Give this man place; and thou begin with shame to take the lowest room.

Luk 14:10 But when thou art bidden, go and sit down in the lowest room; that when he that bade thee cometh, he may say unto thee, Friend, go up higher: then shalt thou have worship in the presence of them that sit at meat with thee.

Luk 14:11 For whosoever exalteth himself shall be abased; and he that humbleth himself shall be exalted.
